and

Figure 8 is a sectional view taken along the plane indicated by thearrows H of Figure 7.

Referring first to Figure 1, the numeral II indicates a blank which maybe made from a sheet REiSSUED "2R 7 1950 of cardboard or the like. Theparticular blank chosen for illustration is intended for a carton havinguniform rectangular cross section throughout its length with end wallsdisposed in right angular relationship with the side walls though theinvention is equally applicable to cartons having tapering walls, thatis, cartons of the nesting type, as illustrated, for example, inapplicants Patent No. 2,390,909 patented December 11, 1945. Secured tothe under surface of the blank as illustrated in Figure 1, which will bethe inner surface thereof when the'blank is shaped into a carton, is theliner ll. Said liner will be adhesiveiy attached to the blank llthroughout the area of said liner except at regions adjacent to thecrease lines of said blank, as will be explained presently.

The blank l0 chosen for illustration is generally rectangular inoutline, the top and bottom edges lying in the parallel lines MA and "Brespectively. Said blank has the parallel side edges 12 and i3 and isprovided with the spaced crease lines I4, I, it and I1. Crease line H isspaced from the side edge l2 and the crease line It is spaced from thecrease line I! to provide either the front or rear wall of the carton.Crease line I! is spaced from the crease line it and the crease line I!is spaced from the crease line I to provide each of the two oppositenarrow side walls of the carton. The space between the crease line l1and the edge I3 is a connector section and is utilized for securing theblank into a continuous outline rectangular in cross section. The partof the blank ill between the edge I! and the crease line ll provides therelatively wide wall or panel l8, referred to hereinafter as the firstwall or panel. The portion between the crease lines II and it providesthe relatively narrow wall or panel l9, referred to hereinafter as thesecond wall or panel. The portion between the crease lines l5 and I6provides the relatively wide wall or panel 20, referred to hereinafteras the third wall or panel, and the portion between the crease lines l6and i1 provides the relatively narrow wall or panel 2i, referred tohereinafter as the fourth wall or panel. The portion between the creaseline I! and the edge It, indicated by the numeral 22, is a connectorsection and is adapted to be adhesively secured to the wall or panel It.

The top and bottom edges of panel It (the first panel) are defined bythe crease lines 22 and 24, respectively. The top and bottom edges ofthe panel I! (the second panel) are defined by the crease lines 25 and28, respectively. The top and bottom edges of the panel 20 (thethirdpanel) are defined by the crease lines 21 and 28. The top andbottom edges of panel 2 I (the fourth panel) are defined by the creaselines 28 and ill. The top and bottom edges of the connector sec- 25 and29, the crease lines 25 and 29 being in alignment with each other. Thecrease line 3| may be in alignment with the crease lines 25 and 29. Thecrease line 23 will preferably be slightly 1 lower than the crease lines25 and 29. These differences in the levels of the crease lines 23, 25,29, and 3| will facilitate the folding of the top closure, as Wm appearpresently. The difference in level of the crease line 21, with respectto the crease lines 25 and 29, will be approximately twice the thicknessof the material of the blank. The level of the crease lines 25 and 29will be spaced above the level of the crease line 23 approximately thethickness of said material.

The portion of the blank below the crease lines 24, 25, 28, 38 and 32will provide the bottom closure of the carton. The details of thisbottom closure form no part of the present invention but are describedand claimed in applicant's copending application Serial No. 750,954,filed May 28, 1947. However, the bottom closure of the carton may takeany preferred form as, for example, that disclosed in Patent 2,390,909dated December 11, 1945; or the-top closure described and claimed inthis application may be used if desired. I

The crease lines l4, l5, I5, I1, 23, 21, 3|, 24, 25, 28, 38 and 32 willbe ruled into the blank |8 on the undersurface thereof as the blank isviewed in Figure 1 so that said crease lines will bias the parts at thesides thereof to bend inwardly, that is, toward the bottom side of theblank as viewed in Figure 1. Crease lines 25 and 29 will be ruled infrom the top side of the blank as viewed in Figur 1.

the blank as viewed in Figure 1 will be referred to as reverse creaselines.

Located above the panel l8 and swingingly connected thereto along thecrease line 23 is a flap 33 having the edge 34 (offset slightly toward 1the right from the edge l2) the edge 35, the edge 35, and the creaseline 31.

crease line 31 are in alignment with each other 55 but are ofisetslightly toward the left from the Said edge 35 and crease line Hi.

The panel 28 (the third panel) is provided with the flap 38 swinginglyconnected thereto along the crease line 21, which flap 38 is defined byIn this disclosure those crease lines: ruled in from the bottom side ofthe blank will the crease line ii. The edge 44 and the crease line 48terminate at the broken line 49. The region bounded by the edge 44, thebroken line 49, the crease line and the crease line '39 is a webindicated by the numeral 42a. g

The tab '43 extending from the right hand extremity of the fiap 38 issymmetrical with the tab 42. Said tab 43 is defined by the edge 58extending in 45 degree relationship with the edge 48 from the junctureof edge 48 with crease line 4|; the edge 5|; the edge 52; the edge 53;crease line 54 and the crease line 4|. The edges 58 and 54 terminate atthe broken line 55. The region bounded by the edge 58; broken line .55;crease line 54 and crease line 4| constitutes a web indicated by thenumeral 43a.-

' Joined to the fiap 33 at the right end thereof is the web 55 definedby the crease line 31; the edge 51; the edge 58- and the crease line 58.Said 'web 55 is joined by means of said crease line 59 to the web 58joined to the-panella (second panel). Said crease line 59 extends in 45degree relationship with the crease line from the juncture of saidcrease line 25' with the crease line l4. The web 55 and the web 58provide a web-comer, and the web 58 and web 42a provide anotherwebcorner, which web-corners contribute to the slitproofness of the topclosure of the carton.

The connector section 22 is provided with the flap 5| which is definedby the edge l3; the edge 52; the edge 53; crease line 54 and the edge3|. The edge 53 and crease line 54 are in alignment with each other butare offset slightly toward the right from the crease line H tofacilitate folding of the top closure.

swingingly connected to the panel 2| is the web 55 defined by the creaseline 29; crease line 54; edge 55 (which lies closely adjacent to theedge 53) and crease line 51. Joined to the web 85 is the web 58projecting from the side of the the crease line 21, the crease line 39,the edge 48 and the crease line 4|. Said crease lines are set inwardlyslightly from the crease lines I5 and i5 l respectively. Extending fromthe left end of the fiap 38 is the tab 42 and extending fromthe rightend of the flap 38 is the tab 43. Said tab 42 is defined by the edge 44extending from the juncture of the crease line 39 and the edge 48 in 45degree relationship with the edge 48; the edge 45; the edge 45; the edge41 and the crease line 48. Said crease line 48 is disposed in 45 degreerelationship with the crease line 25 and communicates with theintersection of crease line 25 to crease line l5. As indicated above,the crease line 39 is offset slightly toward the right from flap 6|.Said web 58 is defined by the crease line 51; the edge 59; the edge 18and crease line 54.

The crease lines 54 and 51 are disposed in 45 degree relationship withthe crease line 29 and the extremities-of said crease lines 54 and 51communicate respectively with the juncture of crease line 23 with creaseline I5 and the juncture of crease line 29 with crease line". The Webs43a and and the webs 55 and 58 provide webcorners contributing to thesift-pfoofnessof the upper closure of the carton.

The present invention contemplates the provision of a liner for the fourside walls of the carton which liner is indicated by the numeral ii inFigures 1, 2 and 3. Said liner will be provided with aseries of sets ofscore lines, each of said sets comprising a center score line indicatedby the numeral 1| and a pair of score lines 1212 parallel with butspaced from the center score line 1|. Each score line 1| is intended tobe located in juxtaposition with a crease line l4, l5 or l5 of the blankI8. The

liner I will be adhesively secured to the inner wall of the blank (thatis, the under side as the blank is viewed in Figure 1) but the regionsadjacent to each center score line 1| between the adjacent score lines1212 are left free of adhesive in order that no rupturing of the lineror of the adhesive between the liner and the blank "I will occur whensaid blank is bent along the crease lines l4. I5 and I5.

The mode of operation of the above described embodiment of the presentinvention is substantially as follows:

- Blank l8, as illustrated in Figure 1, may be L section will beadhesively attached to the side of the panel l8 toprovlde a tube ofapproximately rectangular cross sectional contour. The flap I The bottomwall of the carton below the crease line 24, 26, 28, 30 and 32 may befolded to provide a closure for the lower end of said tube, the detailsof this closure forming no partof the present invention. The cartonthereby provided may be filled with material after which the top of thecarton may be closed. The preferred procedure in closing the top of thecarton is as follows:

The upstanding fiap 33. is swung inwardly about the crease line 23 as anaxis into right angular relationship with the wall l3 carrying with itthe flap 6| adhesively attached to said flap 33. This action will swingthe webs 65 and webs 5G and 60 about the crease line 59. The flap 6| aswell as the flap 33 will fit within the top of the carton, forming astrut between the wall l8 and the wall thereof. The web 56 will be swunginto flatwise engagement with the web 80 and the web 58 will be swunginto flatwise engagement with the web 65, said webs 56 and 60 at oneside of the carton and said webs 68 and 65 at the other side of thecarton being swung outwardly with respect to the carton (Figure 5).

The flap 38 will then be swung downwardly into flatwise engagement withthe flap 32 whereby the parts will assume the positions illustrated inFigure 6. Adhesive will be used between the contacting faces, that is,the interfacial surfaces of the flaps 33 and 38 whereby said flaps willbe secured together.

An important feature of the present invention is embodied in theefficient sealing of the webs 68 and 65 with the tab 43 (that is, theweb portion 43a of said tab between the lines 4| and 55), as well as theefllcient sealing of webs 56 and 80 with the tab 42 (that is, the web42a thereof between the lines 39 and 49). Adhesive having been appliedto the contacting surfaces, said webs 68 and 55 will be secured togetherand to the flap 43 and the webs 56 and 60 will be secured together andto the flap 42 by squeezing or gripping actions. The tabs 42 and 43 willthen be drawn down into engagement with the panels l9 and 2|,respectively, drawing the top flap 38 tight across the top of thecarton. At this time sealing pressure is applied across the top of thewill also be adhesively secured to the flap. 33.

68 about the crease line 61 and will swing the 6 sity for using heavymaterials. Said liner may beattachedtothe blank when said blankis infiat condition and may be folded up with the blank without danger ofrupturing of the lineror of the adhesive material between the liner andthe blank;
